Abstract
The efficient water-reducing agent for concrete used for construction of runway, dam or high-grade highway is prepared from waste phenolic dregs from oil refinery through such technological steps as sulfonating the waste phenolic dregs using concentrated sulfuric acid, condensation, neutralization, and spray drying to obtain powder product, and contains mainly alkylphenol-sulfonic acid-aromatic fused ring compound, condensate of formaldehyde sulfonate or amino formaldehyde and sodium sulfate. When it is mixed with concrete by 0.05-0.1 percentage, the water-reducing rate is up to 15-20%.
Description
The invention belongs to the production method of material of construction cement additive, specifically utilize the method for the waste phenol dregs synthesizing efficient cement water reducing agent that refinery emits.
In petroleum refining process, often there is a large amount of useless phenol mixtures to discharge.Its fundamental component is phenol, cresols, xylenol and other aromatic fused ring compounds.This industrial residue is water insoluble, poisonous, during heating in the pitch shape, only reclaim a part at present and be used for preparing the poor efficiency agricultural chemicals, poor because of the Biodegradable of phenol, so environment is caused severe contamination, if directly be disposed in the rivers, then pollution is more abominable.The objective of the invention is to propose a kind of method of utilizing the waste phenol dregs oil refinery synthesizing efficient cement water reducing agent.The discharging of using this method not only can solve waste phenol dregs oil refinery, and control pollution problems, and can obtain the important cement additive of construction sector---efficient cement water reducing agent again.
At present, commercially available efficient cement water reducing agent, adopt naphthalene is raw material more, thereby the production cost height.The present invention directly adopts waste phenol dregs oil refinery, utilizes operations such as sulfonation, condensation, neutralization, spraying drying, makes efficient cement water reducing agent.This water reducer is a chocolate brown powder, when add in the concrete cement amount 0.4% the time, water-reducing rate can reach 15～20%.
The main process and the chemical reaction of this technology are as follows:
1, sulfonation reaction
For explaining conveniently, above-mentioned reaction formula the right is with PhSO
3H represents.
2, condensation reaction:
Or:
3, neutralization reaction:
4, spraying drying forms powder-like product
Implementation process of the present invention is as follows:
With in the oil waste phenol dregs, adding people's sulfuric acid material in 1～5 hour, be warming up to 60～150 ℃ after adding, be incubated 2～8 hours, in 40～100 ℃ temperature range, add people's formaldehyde gradually, the reinforced time was controlled at 1～5 hour, after formaldehyde adds, can further add properties-correcting agent, and under uniform temp, keep reaction 1～10 hour, until reacting completely, be cooled to 30～50 ℃ then, add the people NaOH aqueous solution gradually, make PH=7～9, the product of formation after filtration, spraying drying and make tan powder-product.
In sulfonation reaction, the concentration of the vitriol oil is controlled at 98%, and sulfuric acid should be controlled at the ratio of oil waste phenol dregs: 1.0～3.0: 1.
In condensation reaction, waste phenol dregs: formaldehyde: aminocompound should be controlled at 1: 0.05～0.2: 0～0.3.
Because starting raw material waste phenol dregs oil refinery of the present invention is the mixture of a kind of phenol, cresols, xylenol and other condensed nucleus aromatic compounds.So the efficient cement water reducing agent major ingredient that makes is alkyl phenol sulfonic, aromatic fused ring sulfonic acid and formaldehyde polycondensate and sodium sulfate and aminoresin modifier and sodium sulfate.During use when add cement amount 0.3～0.6% the time, water-reducing rate reaches 15～20%.So be a kind of high efficiency water reducing agent.
Embodiment:
By 98% vitriol oil: the oil waste phenol dregs: the weight ratio of formaldehyde=1.75: 1: 0.2, taking by weighing the 500kg waste phenol dregs puts in the people 2000L enamel still, be heated to 70 ℃, drip the 875kg98% vitriol oil, be warming up to 90～120 ℃ after dripping, be incubated 5 hours, be cooled to 50 ℃ then,, dropwise the back and be warming up to 105 ℃ with 1 hour with the formaldehyde solution that slowly dripped 100kg 37% in 1 hour, be incubated 5 hours, treat that the material thickness can flow, during formaldehydeless flavor, add the neutralization of NaOH solution, make pH=7～9, carry out concentrate drying then, get the chocolate brown powder product.
Technology of the present invention is simple, and is with short production cycle, and raw material is cheap and easy to get, and prepared water reducer can significantly improve concrete performance, saves cement consumption, the reduction of erection time, improves construction quality.
